Any content displayed on pages is editable in templates. You can remove it or I can do it for you.
As of the api connection, please send me details, I will check it out. Use the contact form at http://www.phpwebscripts.com/contact.html. Also note that it's possible to show 3rd party ads even without any api features. You can get their ad html or javascript code and put it to the ad edit form in admin area. There is available a html ad field which is meant to be used for such purposes.

Ads in Individual Zones all zones showing in publisher panel.
How can I edit this to shown only particular one or two zone types in a publishers's account so that they can use the two types of ad code for their earning.
Example: I want to show
1. Banners Full Size 300x50
2. Onclick popunder window example
3. Onclick popunder window example_________________Adknock Pvt. Ltd.

Please edit the zones which should be hidden in admin area => zones. Enter 0 to the field "Publishers earn". Then publishers can't use nor see these zones nor ad types. Alternatively you also can delete the zones at all and optionally also can delete the ad types.
